Abstract

The invention relates to a motor snow sledge comprising a structure similar to that of a child's tricycle, including two rear skis and one front ski serving as supporting points, a seat installed on the structure and a steering system in the form of handlebars which steer the front ski. The sledge includes a system of pedal brakes built into the rear skis, which enables a blade to be inserted gradually into the snow, as well as a system of paddle brakes abutting against the lower part of the structure and actuated manually using a handle on the steering system. The vehicle can travel up a slope by means of a traction unit consisting of a retractable motor-driven caterpillar track installed beneath the seat.

Description

DESCRIPTIVE MEMORY

1.- OBJECTIVE OF THE UTILITY MODEL

People who do not have the proper physical condition are deprived of the possibility of practicing snow skidding. This utility model aims to cover this deficit, providing a means of practice, which does not require having a physical state and / or prior training, with a safe practice, and at a reasonable cost.

2.- DESCRIPTION OF THE KNOWN IN THE MATTER

We will analyze the different competitors or similar products that the Motorized Snow Sled currently has. Basically these are equipment that are now leased in ski resorts (in the case of skis) and / or sold in specialized stores abroad (for bicycles and motorcycles).

2.1.- Skis.

Skiing is a mountain sport that consists of sliding through the snow, by means of two boards attached to the sole of the skier's boots by means of mechanical fasteners. This sport requires great effort and physical ability. The use of mechanical fasteners and special boots makes the equipment even more expensive. These devices do not have braking devices, rather their arrest depends on the inclination of the edge of the skis against the slope, increasing the area of friction. Therefore, it requires a degree of expertise.

2.2.- Snowboard

The snowboard, or snowboard, has been added to the ski, in which the person places both feet on a single surface, so it requires more balance.

The required expertise is even greater in snowboarding, as the supports are still two, but they are online, so it requires a great job of waist and legs. These teams also do not have brake devices, and their braking is done by varying the position with respect to the axis of displacement, increasing the inclination of the edge of the board against the slope, which in turn generates an increase in the force of touch.

2.3. Snow Sleds

The sled is one of the oldest equipment used in snow. Its various applications have made it widely used, both by military mountain forces and by children and adults to entertain themselves. There are wooden, plastic and even stainless steel. They reach high speeds on steep and medium slopes. They are not very safe, do not incorporate brake mechanisms and are not comfortable from the ergonomic point of view. Its greatest use is for children, on very soft slopes and guided by an adult. 2.4 Snow Bike.

Snow bicycles are designed and built in European cities such as Zurich, Pyrenees and Madrid. Today there are groups and / or competition leagues, which are held in different cities of the old continent. These teams have an aluminum structure, with the ability (in some cases) to disassemble completely, and two skis arranged one in front of the other, replacing the wheels of a traditional bicycle. In addition, consider two small, independent skis, which with the traditional ski shoes and fixings, go on each foot of the skier. In this way, it has four points of support. The skis are made of fully polished wood, covered with fiberglass. This achieves greater durability of skis. As regards its practice, we must say that this mobile requires a high degree of skill and physical effort. Therefore it is recommended only for young people with good physical condition since, in addition, it does not have brakes, which makes its practice even more difficult. Both its high price and the exchange rate become an entry barrier, and this is one of the reasons why these teams have not yet arrived in Chile.

2.5.- Snow and Sand Bike

This bicycle model can be used in both snow and sand. Its construction is very simple. It consists of a common and current bicycle to which the necessary accessories are adapted. In the front part there is a wooden ski covered with fiberglass and in the rear part a wheel with a traction system. Energy is provided by the driver, when pedaling, transferring to a drive belt. The braking system acts only on the traction belt, so it is quite deficient when facing slopes in favor, in hard snow. 2.6.- Snowmobiles

They are the most comfortable and least demanding devices, in terms of physical and / or athletic condition. They allow the person to sit comfortably. They are not designed to slide freely, since the movement is permanently based on the traction of its drive mechanism.

Being very comfortable, they are very expensive, varying their price between 8,000 and 12,000 US dollars.

On the other hand, they prevent enjoying the silent displacement, due to the loud noise of its engine.

Models manufactured by Yamaha and other major manufacturers have incorporated high-tech impact damping systems, which makes driving very enjoyable, although it greatly increases its price.

3.- DETAILED DESCRIPTION OF THE UTILITY MODEL.

The Motorized Snow Sled has a structure equivalent to a children's tricycle, but with a modified design to incorporate skis, instead of wheels. In this way, people interested in practicing landslides on snow are oriented, but who lack the equipment and / or physical condition necessary for their traditional practice.

The rear skis (N ⁰ 9 of Drawing 1) are fixed, while the front ski (N ⁰ 4 of Drawing 1 and N ⁰ 6 of Drawing 2) has movement, being attached to a steering wheel (N ⁰ 2 of Drawing 1 and N ⁰ 2 of Drawing 2).

The utility model described in this document is designed to move in hard snow, taking advantage of slopes or slopes, that is, using the force of gravity. To this model, a track mounted on polines has been incorporated (N ⁰ 5 of Drawing 1 and N ⁰ 7 of Drawing 2), driven by a drive system (N ⁰ 11 of Drawing 1), to go against the slope.

The utility model (hereinafter referred to as "Motorized Snow Sled") has a double brake system: the first brake device (N ⁰ 6 of Drawing 1, N ⁰ 4 of Drawing 2 and N ⁰ 4 of Drawing 3) It is incorporated in the rear skis, allowing a gradual braking activated with the feet, while the second brake device (N ⁰ 10 of Drawing 1 and N ⁰ 1 of Drawing 3) is attached to the lower rear part of the structure, and It is activated manually from the steering wheel (N ⁰ 14 of Drawing 1 and N ⁰ 10 of Drawing 2).

This Motorized Snow Sled is made up of the following parts and / or components: 1.1.- A metal structure (N ⁰ 8 of Drawing 1 and N ⁰ 8 of Drawing 2), which gives strength to the whole. In this framework, each of the necessary elements is assembled, incorporating the rear brake elements (N ⁰ 10 of Drawing 1 and N ⁰ 1 of Drawing 3), the motorized track system (N ⁰ 5 and N ⁰ 1 1 of Drawing 1 and N ⁰ 7 of Drawing 2), the pvc tray seat, with backrest (N ⁰ 12 of Drawing 1 and N ⁰ 3 of Drawing 2), and a flag bar (N ⁰ 1 of Drawing 1 and N ⁰ 1 of Drawing 2).

1.2.- Three skis, in which the central front ski (N ⁰ 4 of Drawing 1 and N ⁰ 6 of Drawing 2) is installed in a handlebar type element (N ⁰ 2 of Drawing 1 and N ⁰ 2 of Drawing 2), which allows to direct the trajectory. The rear skis are equipped with a pedal brake system (N ⁰ 6 of Drawing 1 and N ⁰ 4 of Drawing 2 and N ⁰ 4 of Drawing 3), with detailed positions in N ⁰ 4.1 and 4.2 of Drawing 3.

3.- DESCRIPTION OF THE DRAWINGS.

In order to adequately describe the Utility Model, four explanatory drawings have been made, which are the following:

• Drawing 1: Side View of the Motorized Snow Sled and its components

• Drawing 2: Front View of the Motorized Snow Sled and its components

• Drawing 3: Detail of the Motorized Snow Sled Brakes

• Drawing 4: Detail of the lifting mechanism of the track.

In drawings 3 and 4 some views of important details have been incorporated into the operation of the Utility Model, aimed at explaining the dynamic behavior of some components.

3.1. - Drawing 3: Details of Dynamic Brake Behavior

A detail of the work of the two types of brakes possessed by the Motorized Snow Sled is shown in Drawing 3:

The foot-activated brake (N ⁰ 4 of Drawing 3) has an inactive position (Drawing 4.1 of Drawing 3), corresponding to the absence of foot pressure. When the heel exerts pressure, lower pedal and introduced in the snow (N ⁰ 4.2 Drawing 3) a blade type knife brake, by the shape of the sheet, generates a gradual braking. The manually activated brake transmits the movement of the hand, like the well-known bicycle brake, by means of an accelerated bolt (N ⁰ 3 of Drawing 3) to the rear brake paddle (N ⁰ 1 of Drawing 3), causing This rotation on the axis of support (N ⁰ 2 of Drawing 3) of the structure, which is fixed by a semi-clamp, generating the braking when increasing friction.

3.2 Drawing 4: Detail of the lifting mechanism of the track.

When the Motorized Snow Sled slides in favor of the slope, the weight of the snow tricycle resides on the skis and the track is lifted and does not touch the snow. To achieve lift Ia caterpillar, the support rods set caterpillar-purlins are hinged and joined to the brake rod (N ⁰ 4 Drawing 4) Ia that is commanded by lever Ia brake (N ⁰ 5 Drawing A) .

Position 1 (N ⁰ 1 of Drawing 4) allows the track to lower, coming into contact with the snow, for landslides against the slope and / or to enable the driving work of the track. Position 2 (N ⁰ 2 of Drawing 4) generates a lifting of the track, for landslides in favor of the slope, which do not require mechanical work of the track.
